Answer 1

The correct answer is option (b) Internal energy.

• The internal energy of the thermodynamic system energy is contained in it. It is the power required to create or modify a system in any internal environment.
• It does not include the kinetic energy of the movement of the whole system, or the potential energy of the whole system due to external power fields, including the potential for removal of the system's surrounding environment. Maintains an account of the gains and losses of the system due to changes in its internal state. Internal force is measured as the difference from zero references to the normal state.

Answer 2

The energy in storage is represents by (b) internal energy.

Explanation:

1.Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules.

2. Internal energy also includes the energy in all the chemical bonds. For example, a room temperature glass of water sitting on a table has no apparent energy, either potential or kinetic.

3.The Change in Internal Energy Formula is: ΔU = Q + W. Here, U = the total change in internal energy within the system. Q = the heat exchanged between a system and its surroundings (outside the system)
